摘要

本論文分成兩部份加以敘述:
(一)合成含稀土金屬的新穎液型添加劑
本研究採用新穎方法將無機稀土鑭系金屬氧化物Ln2O3反應為
Ln(OOC-R)3，並探討如何使其成為液狀的均勻相，使便於添加至PVC
粉中，作為一種新穎的添加劑。

(二)新穎金屬羧酸鹽液體添加劑對PVC性能之探討
以所合成的有機羧酸錯合物Ln(OOC-R)3，分別以不同添加量加至無毒液狀的鈣鋅系的PVC安定劑內，再以此混合型液體添加劑加至
PVC(MW=1000)粉內，作成品測試探討，以此對照當PVC粉經加入各
種添加劑時，在使用前後的各項PVC的物性探討，包括PVC加工時之
耐熱性、流變性及加工成型的產品之光學特性、電阻特性、抗UV老化特性等性能上的影響。

The content of this thesis is described as follows:
( Ι ) Synthesis of Novel Carboxylate Additive
This research introduces a new approache to successfully esterify the rare-earth metal oxide (Ln2O3) into Ln(OOC-R)3. We have also been explored how to make it be liquefied in a uniform phase, then that can be applied easily as a new additive for PVC.
(II)The Influence of Novel Metal Carboxylate Additives on PVC Plastic Production
First, the new additive Ln(OOC-R)3 was added in several different amounts with the non-toxic liquified calcium-zinc stabilizer. Then, apply the serious complex stabilizers be added into the PVC(MW=1000) resin plastic powder, and that were prepared in PVC sheets. Furthermore, their physical properties of PVC with various additions of additive components have been examined by several instruments. The heat stability of the PVC sheets were studied by thermogravic weight loss analysis (TGA) tests. During each samples of PVC were being processed their rheological properties were be examined and further compared. for deeply exploring the influence of the new additive. We have further examined several properties of the final products of PVC sheets. We have studied the novel benefits of Ln(OOC-R)3 as an additive for the properties of PVC, that included the optical properties and the electric insulation properties and anti-aging properties.
